Climate Change & Clean Energy


In 2014, a renewed EU Fluorinated Greenhouse Gases Regulation No 517/2014 (or “F-Gas Regulation”) was adopted to reduce fluorinated gas emissions by two-thirds by 2030, as compared with 2014 levels. This reduction supports EU obligations under the 2016 United Nations Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer (1987). While the phase-down is ongoing, replacing fluorinated gases with climate-friendly alternatives is becoming difficult. Safety standards drastically limit the use of climate-friendly alternatives such as natural refrigerants because of their flammable properties, without reflecting technological developments able to mitigate the risks. ECOS works at both European and international level to reduce the barriers posed by standards to the uptake of natural refrigerants, thus improving the environmental performance of the heating and cooling sector.

What we are working on

  • Life FRONT, a 3-year demonstration project co-funded by the European Union’s Life Programme and aiming at removing barriers posed by standards to flammable refrigerants through lab testing and simulations:;
  • Revision of horizontal standards EN 378 and ISO 5149 setting safety and environmental requirements of refrigerating systems and heat pumps;
  • Following up on the standardisation developments following the European Commission Standardisation Request (M/555) on natural refrigerants;
  • Contribution to the standardisation developments related to the safety of appliances using refrigerants (including the EN 60335 standard series);
  • Making sure that the outcome of F-Gas Regulation Art. 11(6) is achieved, and to ensure consistency between regulatory and standardisation developments;
  • Continued cooperation with the European environmental civil society working on fluorinated gases.

    By 2050, two thirds of the world’s households could have an air conditioner due to the effects of global warming. According to the International Energy Agency, the total number of air conditioners is expected to grow from 1.6 to 5.6 billion globally. The need to switch to climate-friendly refrigerants has never been so great!

  • Let’s keep fossil fuels out of green investments!

    Last June, the European Commission Technical Expert Group (TEG) published the first draft of the Taxonomy Technical Report, a classification of economic activities that could be claimed as environmentally sustainable. Even though in includes ambitious criteria for certain activities, we have serious concerns about the presence of dirty fossil fuels and the lack of fundamental sustainability requirements for other proposed activities.

  • Air conditioners and comfort fans: stop protecting inefficient technologies!

    The rising temperatures and increasing frequency of heat waves result in a growing number of air conditioner and comfort fan units. These, in turn, contribute to direct GHG emissions from the intensive energy consumption and refrigerant leakage.
